BACKGROUND OF THE INVENTION

A wide variety of solid, liquid and gaseous functional materials including body deodorants, anti-perspirants, anti-perspirant/body deodorant devices, air fresheners which include air freshening devices, and solid and liquid air freshening and room freshening compositions, room deodorants, herbicides, antiviral compositions, fungicides, bactericides, parasiticides, insecticides, depilatory compositions, bleach compositions, hard surface-cleaning compositions, skin cleansing compositions, anti-microbial nail preparations including anti-fungal nail lacquers, hair setting compositions, hair conditioning compositions, trichological lotions, detergent compositions, soap compositions, sunscreen compositions, fabric stain-removal compositions, fabric softener compositions, fabric conditioning compositions, fabric anti-wrinkle compositions, skin softening compositions, skin texture enhancement compositions, such as line and wrinkle corrective compositions, skin lightening compositions, steam iron aroma compositions including stress relief compositions, candle compositions, plant growth regulating compositions, plant growth stimulating compositions, fertilizer compositions, insect attractant compositions, insect repelling compositions, drain cleaning compositions and molluskicide compositions have been developed that, although useful for their respective purposes, on use thereof emanate odours which are offensive to the human sense of smell.

In addition, a number of defined 3-dimensional spaces the use of which is required for various business and service operations and personal matters including indoor gymnasiums, indoor sporting event arenas, locker rooms, hair salons, nail salons, tanning salons, beauty salons, tattoo parlors, pig pens, chicken coops, cow barn enclosures, horse barn enclosures, indoor fresh fish markets, plant processing factory rooms, clothing dry cleaning rooms, garment laundry interiors, rooms containing in-use animal litter containers, abattoirs, cattle cars, zoo animal pens, morgues, autopsy rooms, lavatories, medical patient care rooms, hospital wards and dental patient care rooms have continuously prevailing odours which are offensive to the human sense of smell. Such odors which are offensive to the human sense of smell are caused by aliphatic halohydrins, aliphatic amines, aliphatic N-oxides, dialkylamines, cycloaliphatic amines, cycloaliphatic N-oxides, cyclo-olefinic amines, cyclo-olefinic N-oxides, cycloaromatic amines, cycloaromatic N-oxides, hydroxyalkylamines, imine compounds, amide compounds, amino acids, polypeptides, modified antimicrobial proteins, diureides, nitriles, aliphatic mercaptans, cycloaliphatic mercaptans, mercaptoalkanoic acids, mercaptoalkanoic acid esters, aliphatic monosulfides, disulfides, trisulfides, sulfur oxides, sulfones and sultones, cycloaliphatic monosulfides, disulfides, trisulfides, sulfur oxides, sulfones and sultones, cyclo-olefinic monosulfides, disulfides, trisulfides, sulfur oxides, sulfones and sultones, cycloaromatic monosulfides, disulfides, trisulfides, sulfur oxides, sulfones and sultones, alkali metal sulfites, bisulfites and metabisulfites, isothiocyanates, thiocyanates, dithiocyanates, isothiazolones, isothiazolinones, thiodiazinethiones, halosulfamates, aryl sulfonamides, lower aliphatic carboxylic acids, phenols, phosphines, aliphatic phosphites and phosphonates, cycloaliphatic phosphites and phosphonates, arsines, lower alcohols, lower ketones, hops, hops acids, aryl pyrazoles, oxazolines, isocyanurates, biguanides, extracts of krameria, hydantoins, pyrollidones, pyrollidone carboxylic acids, pyrollidone carboxylic acid esters, nitrophenols, N-substituted aspartic acids and pyrethroids. Compounds of these classes that have unpleasant odours are referred to herein as malodor compounds.

The aforementioned functional materials are known to include and/or have applied thereto or in a 3-dimensional space proximate thereto, fragrance materials that are intended to provide pleasant fragrances which mask the malodor.

In addition, the aforementioned defined 3-dimensional spaces are known to have introduced therein compositions such as fragrance materials that are intended to provide pleasant aromas which mask the malodor, present therein and/or introduced thereto.

The masking effect is provided by one of three mechanisms. In the first mechanism, the masking composition components blend with the malodor compound or compounds in an effort to effect formation of a different and more desirable aroma. In the second mechanism the masking composition components are employed in a large quantity and concentration whereby the compound or composition responsible for the malodor is overwhelmed. In the third mechanism, one or more masking composition components overwhelm the compound or composition responsible for the malodor and one or more masking composition components chemically react with the malodor compound or composition thereby effecting formation of a more desirable aroma.

Each of the aforementioned mechanisms have serious disadvantages. Thus, in the case where a fragrance composition is used as a malodor maskant, it will not completely eliminate the perception of malodor and, accordingly, there is a tendency to use increasing quantities and concentrations of fragrance in an effort to eliminate the perception of malodor. Furthermore, the masking effect is an additive effect and so the total odor level in the malodor-masked functional product or in the malodor-masked defined 3-dimensional space is increased by consumption of the fragrance. Even though the fragrance so used may be very pleasant at low concentration, the total odour level in the 3-dimensional space proximate the in-use functional product and the total odour level in the aforementioned defined 3-dimensional space at the relatively high concentrations required to achieve even moderate masking of the malodor will itself be offensive to the human sense of smell.

The prior art contains evidence of a large number of efforts to overcome the aforementioned disadvantages.

Thus, the use of zinc ricinoleate, also known as TEGO Sorb (Goldschmidt A. G. of Essen, Germany) for suppressing malodors is disclosed in U.S. Pat. No. 6,528,047, U.S. Pat. No. 6,592,813, U.S. Pat. No. 4,968,496 and U.S. Patent Application 2003/007945 A1 published on Jan. 9, 2003. Furthermore the, use of one or more of the substituted cyclic organic compounds:

-   1-cyclohexylethan-1-yl butyrate; -   1-cyclohexylethan-1-yl acetate; -   1-cyclohexylethan-1-ol; -   1-(4′-methylethyl)cyclohexylethan-1-yl propionate; and/or -   2′-hydroxy-1′-ethyl(2-phenoxy)acetate     sold under VEILEX (International Flavors & Fragrances Inc., New     York, N.Y.) for suppressing malodors are disclosed in, for example,     in U.S. Pat. No. 6,432,891, U.S. Pat. No. 6,592,813 and U.S. Pat.     No. 4,622,221.

Furthermore the use of zinc ricinoleate in functional substance such as fragrance containing polyamide sticks and packages dispensing same are disclosed in U.S. patent application Ser. No. 10/683,525 filed on Oct. 10, 2003 but no mention is made therein of the use of polyamide sticks for malodor suppression or prevention.

A preferred substituted monocyclic organic compound composition useful in combination with the zinc ricinoleate component is a mixture of:

-   (A) 1-cyclohexylethan-1-yl butyrate; -   (B) 1-cyclohexylethan-1-yl acetate; and -   (C) 1-(4′-methylethyl)cyclohexylethan-1-yl propionate.

Preferably, the synergistically-effective zinc ricinoleate-substituted monocyclic organic compound-containing malodor preventing and/or suppressing compositions are employed in compatible solvents prior to the composition being incorporated into functional products. Such compatible solvents are, preferably, 1,2-propylene glycol, and di(1,2-dihydroxypropyl)ether, commonly known as dipropylene glycol or DPG. The range of dilution of the zinc ricinoleate-substituted monocyclic organic compound-containing malodor preventing and/or suppressing compositions in the compatible solvents is from about 2% to about 50% by weight of the zinc ricinoleate-containing composition of our invention, preferably from about 10% to about 30% and most preferably about 15% by weight of the zinc ricinoleate-containing composition of our invention.

When used in conjunction with malodorous solid or liquid functional products, e.g., soap and detergent compositions, the synergistically effective zinc ricinoleate-substituted monocyclic organic compound-containing malodor preventing and/or suppressing mixtures of our invention may be employed in a concentration of from about 75 ppm to about 300 ppm based on the weight of the solid or liquid composition preferably from about 100 ppm to about 250 ppm.

When used in conjunction with malodorous gaseous functional products, the synergistically effective zinc ricinoleate-substituted monocyclic organic compound-containing malodor preventing and/or suppressing mixtures of our invention may comprise from about 1.0 gram/liter to about 5.0 grams/liter, preferably from about 1.5 grams/liter to about 3.0 grams/liter of the air 3-dimensional space which contains the malodor to be counteracted.

As stated above, the functional products with which the zinc ricinoleate-substituted monocyclic organic compound compositions of our invention may be used also may optionally include fragrances, anti-microbial substances, animal repellents, insect attractants, and insect repellents, each of the components of which has a C log₁₀P in the range of from about 3.0 to about 8.0, without restriction on the molecular weight of each of said components wherein P is the n-octanol/water partition coefficient of the fragrance component. Examples of fragrance/anti-microbial compositions useful in the practice of our invention are set forth in U.S. Pat. No. 6,495,512 and U.S. Pat. No. 6,517,759.

The values of C log₁₀P of many functional product ingredients, for example, fragrance ingredients and/or antimicrobial ingredients, contained in personal treatment compositions and/or cosmetic compositions is discussed in U.S. Patent Application US 2003/0110682 A1 published on Jun. 19, 2003, U.S. Pat. No. 5,348,667, U.S. Pat. No. 5,652,206 and U.S. Pat. No. 6,528,013. Furthermore, values of log₁₀P have been reported; for example, the Pomona92 database, available from Daylight Chemical Information Systems, Inc., Daylight CIS, Irvine, Calif. However, the log₁₀P values are most conveniently calculated by the “CLOGP” program, also available from Daylight CIS. This program also lists experimental log₁₀P values when they are available in the Pomona92 database. The calculated log₁₀P (C log₁₀P) is determined by the Hansch and Leo “fragment” approach based on the chemical structure of each perfume ingredient, and takes into account the numbers and types of atoms, the atom connectivity and the chemical bonding. The C log₁₀P values which are the most reliable and widely used estimates for this physicochemical property, are preferably used instead of the experimental log₁₀P values for the selection of functional ingredients, including perfume ingredients which are useful in the stick articles of our invention.

Specific examples of preferred fragrance components useful in the stick articles of our invention, and the molecular weights and C log₁₀P values of each of said components are set forth in Table II as follows

DETAILED DESCRIPTION OF THE DRAWINGS

Referring to FIG. 1 and FIG. 2, the package 1 is adapted for use with the malodor-suppressing stick article comprising a removable cap 2 for closing the package to protect the product therein. The cap is removed to permit application of the malodor-suppressing product with optional fragrance composition contained in the ETPA and/or ATPA to an inanimate solid laminar surface, e.g., a garbage bag or porcelain sink surface. The package 1 further comprises a barrel 3 containing the malodor-suppressing stick article 4 of our invention. The wall of the barrel 3 closely surrounds the stick article 4. An applicator 5 having an upwardly facing applicator surface 6 is formed integrally with the barrel 3 at the top end thereof. The lower end or bottom 8 of the stick 4 is supported within the package on an oval-shaped, movable support member 9 for movement up or down within the package relative to the barrel 3. A central portion of the movable support member 9 is provided with a threaded coupling sleeve 10 for cooperation with an elevator screw 11. The lower end of the elevator screw is axially fixed but rotatable within an opening in the closed, bottom end of the barrel 3. The elevator screw 11 includes a tapered section 13 which can be snap fitted within the opening using resilient tabs 20, in the bottom of the barrel 3 to retain the elevator screw 11 in the position shown in FIG. 2 while permitting the screw to be rotated by means of a knob 14 provided on the lower end of the screw. The bottom of the barrel 3 is dished inwardly to accommodate the knob 14 so that the package 1 can stand upright with the lower, outer, peripheral portion of the barrel, 3, resting on a flat supporting surface. Rotation of the knob 14 permits the user to raise or lower the movable support member 9 relative to the barrel 3 and thus raise and lower the malodor-suppressing stick article 4 of our invention relative to the barrel 3. The stick article 4 is shown in its lowered position in FIG. 2 with the top of the stick flush with the applicator surface 6. The several components of the package 1, including the cap 2, barrel 3, applicator 5 and coupling sleeve 10 are preferably each formed of plastic, e.g., polypropylene or high density polyethylene including talc-filled polypropylene using techniques well-known to those skilled in the art. The outer surface portion of the applicator surface 6 is rounded, curved downward, for reducing drag during application of the polyamide-containing malodor-suppressing/optional fragrance (and/or additional functional ingredient, e.g., insect repellent) composition contained in the stick article to the inanimate solid laminar surface being treated. The outer surface portion ends in free end 15, which is below the applicator surface edge adjacent the barrel. The outer surface portion part that downwardly extends to free end 15 of the applicator is a cooperating surface upon which the lower skirt 16 of the cap 2 can be slidably fitted and removed with slight resistance. The cap 2 can have ribs 27 associated therewith to maintain the cap in a proper position relative to the barrel 3.

Referring to FIG. 3, the malodor-suppressing stick article of our invention, 32, having application surface 33 is contained in package 30 which has a retaining wall 34 surrounding stick article 32. Holding wall 35, the purpose of which is to provide a convenient surface for an individual using package 30 in applying polyamide-containing malodor-suppressing/optional fragrance composition from stick article 33 to an inanimate solid laminar surface, e.g., a garbage bag or porcelain toilet bowl surface, surrounds retaining wall 34 in close proximity thereto and is juxtaposed thereto. As the stick article 32 is used during application to the inanimate solid laminar surface, it is moved by the user upward past retaining wall 34 using the rotatable manual positioning knob 31 which rotates about the vertical axis of package 30 as the stick article 32 moves up and down relative to retainer wall 34.

The same examples are carried out (a) in the absence of the TEGO Sorb but in the presence of the 10:10:10:10 mixture of 1-cyclohexylethan-1-yl butyrate, 1-cyclohexylethan-1-yl acetate, 1-(4′-methylethyl)cyclohexylethan-1-yl propionate and 2′-hydroxy-1′-ethyl(2-phenoxy)acetate and (b) in the absence of any malodour blocking compounds but in the presence of the TEGO Sorb. In each example that is carried out in the absence of TEGO Sorb and the presence of the 10:10:10:10 mixture of 1-cyclohexylethan-1-yl butyrate, 1-cyclohexylethan-1-yl acetate, 144-methylethyl)cyclohexylethan-1-yl propionate and 2′-hydroxy-1′-ethyl(2-phenoxy)acetate the “V” values are 3.9 for Example IVA without the TEGO Sorb, 3.8 for Example IVB without the TEGO Sorb and 3.65 for Example IVC without the TEGO Sorb. In each example that is carried out in the absence of any malodor blocking compound but in the presence of TEGO Sorb, the “V” values are 4.95 without any malodor blocking compound for Example IVA, 4.85 without any malodor blocking compound for Example IVB and 4.70 without any malodor blocking compound for Example IVC. This example demonstrates the superiority and synergism of the combination of TEGO Sorb when used with a 10:10:10:10 mixture of 1-cyclohexylethan-1-yl butyrate, 1-cyclohexylethan-1-yl acetate, 1-(4′-methylethyl)cyclohexylethan-1-yl propionate and 2′-hydroxy-1′-ethyl(2-phenoxy)acetate, as opposed to using a 10:10:10:10 mixture of 1-cyclohexylethan-1-yl butyrate, 1-cyclohexylethan-1-yl acetate, 1-(4′-methylethyl)cyclohexylethan-1-yl propionate and 2-hydroxy-1′-ethyl(2-phenoxy)acetate alone, or using TEGO Sorb, alone. This example also demonstrates that when using the combination of TEGO Sorb with a 10:10:10:10 mixture of 1-cyclohexylethan-1-yl butyrate, 1-cyclohexylethan-1-yl acetate, 1-(4′-methylethyl)cyclohexylethan-1-yl propionate and 2′-hydroxy-1′-ethyl(2-phenoxy)acetate, a lower concentration of the combination in a molded stick article, such as about 4.75% was found to be more effective than a higher concentration of the combination, such as about 13%.

Example V

Two 1 foot square damp cotton cloth swatches (Identified as Swatch A and Swatch B) and two 1 foot square dry cotton cloth swatches (Identified as Swatch C and Swatch D) were each exposed to cigar smoke evolved from 4 King Edward VII fresh cigars in four separate 3 ft air-tight enclosed chambers for a period of 12 hours thereby imparting an intense tobacco malodor to each swatch. The four swatches were then removed from the chambers and each swatch was separately washed for a wash time of 6 minutes and a rinse time of 2 minutes as follows:

(a) Swatch A and Swatch C:

-   -   A liquid detergent composition was prepared as described in         Example 4 on Page 6 of U.S. Patent Application US 2003/0114323         A1 published on Jun. 19, 2003, containing 99.775% detergent base         (HLB Value of 13.2) and 0.225% of the following mixture:

Ingredients Parts by Weight TEGO Sorb. Conc. 50 10 1-(4′-methylethyl)cyclo- 5 hexylethan-l-yl propionate Dipropylene Glycol 85

(b) Swatch B and Swatch D:

-   -   A liquid detergent composition as described in Example 4 on Page         6 of U.S. Patent Application US 2003/0114323 A1 published on         Jun. 19, 2003, containing 100% detergent base (HLB Value of         13.2).

Each of the swatches were then measured by a 10 member expert panel for tobacco malodor intensity, scaled on a scale of 0-9, and the results are summarized in FIGS. 4A and 4B, described above and set forth on the following table. In addition, the damp cloth swatches, A and B were measured for preference by a 10 member experienced panel, scaled on a scale of 0-14:

Panelist Malodor Intensity Scaled Preference Scaled Cloth Swatch Value (FIGS. 4A and Value Identification 4B) (FIG. 5) A (Damp Cloth-FIG. 4B, 2.3 12 Reference Numeral 45 and FIG. 5, Reference Numeral 53) B (Damp Cloth-FIG. 4B, 8.0 5.2 Reference Numeral 44 and FIG. 5, reference numeral 52) C (Dry Cloth-FIG. 4A, 1.3 — Reference Numeral 43) D (Dry Cloth-FIG. 4A, 7.7 — Reference Numeral 42)

Based upon the scoring criteria set forth above, a lower score is desirable for the malodor intensity and a higher score is more desirable for panelist preference. The test results reported above are consistent in their result. With the combination of TEGO Sorb and malodor blocking compounds, Swatches A and C, the resulting malodor intensity is low and the panelist preference is high. When the TEGO Sorb material is not provided, Swatches B and D, the resulting malodor intensity is high and the panelist preference is low.

Sample Preparation

Malodor: 3% IFF synthetic Garbage Malodor in Diethyl Phthalate (DEP)

Bag Lining Preparation:

-   -   Garbage bag (double film layer) was cut with scissors into two         portions; a rectangle of 2.5×4.5 inch (L×W) dimension and a         circle of 2.2 inch diameter (see figure). Note: Garbage bag         number varies with test so it is indicated with the result         table.     -   The rectangular portion was cut such that the closed edge of the         garbage bag (which was taken from the side of the bag, 12″ from         the bottom) is 2.5 inches and the longer side is 4.5 inches. The         other 2.5 inch edge of rectangular portion was sealed using tape         making the rectangle into a cylinder of 4.5 inch diameter. This         cylindrical tube was placed inside the 8 oz jar to provide         single bag layer interior lining.

-   -   The 2.2 inch circle (which is a single layer taken from 1″ below         the rectangle piece) was placed inside the jar to cover the         bottom of the jar.     -   A glass rod or spatula was used to adjust the lining such that         it covers the sides and bottom of the jar completely. The jar         was labeled with 3-digit blinding code for evaluation.     -   Under a fume hood, the lined jar was placed on weighing scale         and 0.12 g of synthetic garbage malodor was added such that the         malodor fell on the bottom and did not spray on the sides of         jar. The lid was securely placed and the sample jars were not         opened again until the evaluation.     -   All samples jars were prepared 17-19 hours prior to evaluation.

Sample for Analytical:

-   -   The remainder of the bag that was used for sensory testing is         folded and placed in a foil bag.     -   Each sample was sealed in foil bag immediately after use.     -   The samples were submitted to analytical by late afternoon on         the day before the test.

Subjects: 17-21 Sensory Panelists (Female) Trained on Malodor Intensity Evaluation Test Procedure:

-   -   Panelists follow standard procedure for sniffing jars. The jars         were sniffed from a distance of about 3 inches from the top of         the jar for 3 seconds by taking short sniffs.     -   Prior to the test panelists smell the synthetic garbage malodor         presented in a jar lined with untreated film for         familiarization.     -   The sample jars are presented in pairs. Each sample jar         evaluated for malodor intensity using labeled magnitude scale         (LMS) according to the procedure disclosed in         -   Barry G. Green, Gregory S.
